Hi all. I borrowed a SAT pci card which appears to be an old ( blue color circuit ) twinhan. The usual startup sequence of the system hung everytime the card is plugged in. I had to disable the PCI hotplug scripts to get the system to boot. I then followed the instructions in the kernel documentation and modprobed the driver like this: modprobe bttv i2c_hw=1 card=0x71 the system froze hard. I rebooted and retried like this : modprobe bttv i2c_hw=1 card=0x68 the system froze hard again. So I wrote this email as advised in the document. I am using kernel 2.6.11 gentoo.
